Twilight dreams about a black world. However, she sees several little spheres, each with different situations happening. In one, she sees Pinkie Pie going all crazy, in another, she sees that Nightmare Moon has returned. She realizes that what happens around her is a fanfiction.

Really liked this one-shot. Twilight dreaming about fanfic while in one. Priceless. Haha. Good Job.
